MOSCOW , Russia -LRB- CNN -RRB- -- Russian authorities are investigating the recent killing of a model-turned-bodyguard .

Anna Loginova in a photo shoot for the Russian edition of Maxim magazine .

Anna Loginova , a 29-year-old former successful model , ran a private security firm of female bodyguards , highly trained in martial arts , demanding high prices to protect Russian billionaires .

One notable client was Russian boxer Kostya Tszyu .

A carjacker pulled Loginova out of her Porsche Cayenne Sunday in Moscow . Loginova grabbed onto the door handle as the car picked up speed and she was dragged along the street before letting go as the car sped away .

`` An intruder just threw her out of the car '' Russian police stated , `` She grabbed the door handle , but when the car picked up speed , she let go . ''

Her fearlessness proved fatal . Loginova died on the scene from serious cranial injuries . The vehicle was later found abandoned in southern Moscow .

Luxury car theft is common in Moscow . Loginova told Maxim magazine in a recently taped interview that she fought off a car thief just four months ago .

`` I stepped out of my car and closed the door when I suddenly saw a young man near me . He grabbed me by the arm in which I was holding the car keys , '' she was quoted as saying .

`` By reflex , I used a jiu-jitsu technique . I twisted his arm and hit him on the face with my elbow . The guy obviously was not expecting such a reaction . He fell down on the rear windshield , which gave me enough time to grab my gun . He immediately jumped into his Honda and drove away , ''

Those who knew her said she was never deterred by danger .

For many Russians she was a feminine icon , bridging the glamorous world of modeling and the rough underbelly of Russian crime .

`` I think she was kind and sweet , not like a terminator , not like Sigourney Weaver in ` Aliens ' '' said Igor Cherski from Maxim magazine `` but I feel that she was not afraid of anything , there was no fear in her eyes . '' E-mail to a friend
